Data interaction model for power transaction based on CIM

With the increase of power transaction business, traditional power transaction data interaction models cannot fully meet the needs of data interaction. The data model conforming to the power transaction data architecture plays an important role. Data interaction requirements of Chinese electricity market transaction business are analyzed, and the specific method of power transaction data description is given in the IEC-61970 protocol standard. Also a common information model (CIM) for electricity trans-action data interaction is built that conforms to the data interaction architecture. Finally the functional description of the model is built adopting the unified modeling language (UML). Compared with the existing electricity transaction data interaction model, the method is beneficial to reduce the degree of data redundancy, increase the speed of data interaction, and thus improve the transaction efficiency of the electricity market.

Reliable Reputation Review and Secure Energy Transaction of Microgrid Community Based on Hybrid Blockchain

A growing number of prosumers have entered the local power market in response to an increase in the number of residential users who can afford to install distributed energy resources. The traditional microgrid trading platform has many problems, such as low transaction efficiency, the high cost of market maintenance, opaque transactions, and the difficulty of ensuring user privacy, which are not conducive to encouraging users to participate in local electricity trading. A blockchain-based mechanism of microgrid transactions can solve these problems, but the common single-blockchain framework cannot manage user identity. This study thus proposes a mechanism for secure microgrid transactions based on the hybrid blockchain. A hybrid framework consisting of private blockchain and consortium blockchain is first proposed to complete market transactions. The private blockchain stores the identifying information of users and a review of their transactions, while the consortium blockchain is responsible for storing transaction information. The block digest of the private blockchain is stored in the consortium blockchain to prevent information on the private blockchain from being tampered with by the central node. A reputation evaluation algorithm based on user behavior is then developed to evaluate user reputation, which affects the results of the access audit on the private blockchain. The higher a user’s reputation score is, the more benefits he/she can obtain in the transaction process. Finally, an identity-based proxy signcryption algorithm is proposed to help the intelligent management device with limited computing power obtain signcryption information in the transaction process to protect the transaction information. A system analysis showed that the secure transaction mechanism of the microgrid based on the hybrid blockchain boasts many security features, such as privacy, transparency, and imtamperability. The proposed reputation evaluation algorithm can objectively reflect all users’ behaviors through their reputation scores, and the identity-based proxy signcryption algorithm is practical.

Analysis of Taiwan’s Mask Collection and Plan Evasion during the COVID-19 Pandemic

This study established a two-stage dynamic game strategy to analyze how the planned quota and price of masks were set and why mask manufacturing firms on the national mask team (NMT) in Taiwan evaded the plan. Plan evasion occurred when the NMT decided to produce less than the quota set by the government, even though they were incentivized and able to produce more. Taiwan’s experience shows that through the collection of masks and the Name-Based Mask Rationing System, the people’s right to procure masks can be guaranteed; however, to promote market transaction efficiency, the government should adopt a lower quota for the collection of masks and allow firms to freely sell them in the market after they complete their plans. The self-interest of the government played a key role in inducing plan evasion.

Has the Internet increased FDI, economic growth, and trade? Evidence from Asian economies

This study examines the causal relationship between the Internet and economic factors in Asian economies between 1997 and 2017. The economic factors consist of gross domestic product (GDP), foreign direct investment (FDI), imports, and exports. A comparative analysis of East, South, and Western Asia was conducted using a panel vector autoregressive model. The findings show bidirectional causality between FDI and Internet use in South Asia, unidirectional causality from Internet use to FDI in East Asia, and unidirectional causality from FDI to Internet use in Western Asia. Moreover, the findings indicate unidirectional causality from exports to Internet use in East Asia and unidirectional causality from Internet use to exports in South Asia, but no impact in Western Asia. Finally, the results show unidirectional causality from Internet use to GDP in Western Asia. As these results suggest that Internet use has boosted economic performance in Asia, policy makers in the region should improve Internet use with a focus on economic growth, improving transaction efficiency, and facilitating foreign investment.

About the Application of Computer Technology in Internet Finance -- based on the Analysis of the Impact of Venture Capital on Capital Overoffering of listed Companies in Financial Investment

With the further development of computer technology, the era of Internet finance has arrived. Computer technology plays an important role in promoting the development of Internet finance and has also become an important basis for the development of Internet finance. The application of computer technology is conducive to the further improvement of the Internet financial system and the better promotion of transaction efficiency. However, there are also many risks in this process. In the field of financial investment, venture capital plays a very important role in the overoffering of listed companies. In this regard, we should not only improve and upgrade the computing technology, but also control the risks existing in the Internet finance. Therefore, this paper mainly discusses the application of computer technology in Internet finance, and from the perspective of the impact of venture capital in financial investment on capital overoffering of listed companies for in-depth discussion.

Measuring Carbon Market Transaction Efficiency in the Power Industry: An Entropy-Weighted TOPSIS Approach

Carbon emission control is an urgent environmental issue that governments are paying increasing attention to. Improving carbon market transaction efficiency in the context of China’s power industry is important for green growth, low carbon transmission, and the realization of sustainable development goals. We used the entropy-weighted Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) method in this empirical study to analyze the carbon market transaction efficiency of China’s power industry. The results showed that the Beijing carbon market has the highest transaction efficiency, followed by those of Guangdong Province and Shenzhen City. Hubei Province also has a relatively high carbon market transaction volume and turnover; its transaction efficiency ranks fourth. Shanghai, Tianjin, and Chongqing are the lowest-ranked regions, having carbon markets with relatively low trading volume and turnover. We, therefore, recommend that to develop a unified national carbon market, governmental agencies at all levels should equitably allocate carbon; strict regulations and penalties are also needed.

What goes on between customers? A cross-industry study of customer-to-customer interaction (CCI)

PurposeThis study aims to provide service managers and researchers with a deeper understanding of the direct on-site interactions taking place between customers.Design/methodology/approachUsing the Critical Incident Technique (CIT), 284 incidents are analysed to develop a typology of how service customers experience direct on-site CCI.FindingsThe research reveals a wide range of CCI. A typology consisting of nine distinct categories of CCI emerged: (1) shared use space, (2) assigned space and possessions, (3) information provision, (4) assistance, (5) social conversations, (6) disrespectful attitude, (7) queuing discipline, (8) transaction efficiency and (9) undesired customers and ‘camouflaged customers’. These categories can accommodate a multitude of customer behaviours that impact, negatively or positively, on the service experience of other customers.Research limitations/implicationsFuture studies could be conducted following a more inclusive research design capable of gaining CCI insights from employees and managers.Practical implicationsPractitioners can use the typology to systematically identify the full range of specific CCI behaviours affecting their businesses. It also assists them in the analysis and understanding of individual C2C (customer-to-customer) interactions. For academics the typology makes available a comprehensive framework to guide future research into CCI.Originality/valueThe study constitutes the first systematic attempt to classify direct on-site CCI across a wide range of services. The typology, unrestricted by any single-industry bias, is robust and conceptually broad, and therefore highly portable across service industries.

Effect of Transaction Rules on Enterprise Transaction Costs Based on Williamson Transaction Cost Theory in Nanhai, China

The high transaction costs due to the incomplete information and transaction rules of the rural collective construction land (RCCL) market indicate that the government must improve the rural collective construction land market. Transaction rules are an important means for the government to intervene in the market and promote the development of market order, to secure land tenure, and to improve the disclosure of information. Vertical integration may reduce enterprise transaction costs but will increase the governance cost of internal organizations in enterprises. Land commercialization and corporate governance restructuring is a considerable challenge worldwide. Using a field survey in Nanhai district, Guangdong province, China, we estimated how the transaction costs of the RCCL are influenced not only by three dimensions of transaction rules—openness, equity, and justice—but also by the human asset in EC or EJC. Tobit models were constructed, and the results show that (1) the greater number of collective leaders, the higher the enterprise transaction cost (human asset in EC or EJC increases transaction costs of enterprises) and (2) the transaction rules are not sufficiently open or fair, which leads to high costs of market information searching, opportunism, and corruption. The transaction information is not transparent and the lag in transaction supervision mode gives rise to unfair transactions, in which the formation mode of land price is unreasonable. Therefore, we suggest that the transaction rules of RCCL market should be further improved in the three dimensions of openness, equity, and justice. Chinese authorities should strengthen their current efforts to build a more open and fair market by reducing the transaction costs of enterprises and improving the transaction efficiency. Our work provides some insights into the improvement of market efficiency which will contribute to the development of the RCCL market in other areas of China and worldwide.
